Remembering "Operation Match"

50+ Years later, all Scientific Research shows: The
key to long-lasting romance: COMPATIBILITY is STRICT PERSONALITY
SIMILARITY and not "meet other people with similar interests".

At the paper "Perceptions of Ideal and Former Partners' Personality and Similarity" The authors had written".... mismatches in personality
are a frequently mentioned cause for relationship break-up. If former
partners indeed have dissimilar personalities, our findings underline
how difficult it is for many people to select a mate with a similar
personality, or, alternatively, how little value individuals put on
finding a similar partner in terms of personality.The present
study's results, as well as the results found in previous studies (e.g.,
Eastwick & Finkel, 2008), may be used to educate
people, especially singles, about what really matters in long-term
relationships, for instance, similarity in personality, instead of complementarity."

Online
Dating sites have very big databases, in the range of 20,000,000
(twenty million) profiles, so the Big Five model or the HEXACO model are
not enough for predictive purposes. That is why I suggest the 16PF5
test instead and another method to calculate similarity.

High precision in matching algorithms is precisely the key to open the door and leave the infancy of compatibility testing.Without
offering the NORMATIVE 16PF5 (or similar test measuring exactly the 16
personality factors) for serious dating, it will be impossible to
innovate and revolutionize the Online Dating Industry.
